CsPbI₃ perovskite solar cells have potential for tandem applications but are sensitive to moisture. Here, CsPbI₃ cells under high humidity were fabricated using dimethylammonium iodide volatilization for precise annealing and 1,8-diaminooctane passivation to enhance efficiency and stability, achieving 17.7% efficiency.
